Jean-Pierre Mestanza/The Jersey JournalErnesto Martin Mora, 48, was stabbed to death in an apartment at 530 40th St. last night.

A Union City man was stabbed to death in his home last night, police said, and the boyfriend of the man's mother has been charged.

Ernesto Martin Mora, 48, was stabbed multiple times in the torso and upper thigh by Ruben Chavez, 63, after a heated argument turned violent, police said. Mora was apparently stabbed with a 9-inch kitchen knife that was recovered at the scene, 530 40th Street in Union City, where the three of them lived.

There were a number of people at the apartment, drinking and socializing, police said. Chavez was arrested at the scene without incident.

Police say that Chavez apparently felt that he was being disrespected by his girlfriend’s son.

"it’s an unfortunate incident where a life was tragically taken," Hudson County Prosecutor Edward DeFazio said. "There is no indication that the victim was armed in any way."

DeFazio said that alcohol may have played a role in the stabbing, since witnesses told cops that people had been drinking a number of hours prior to the incident.

Mora was pronounced dead at 6:57 p.m. last night at the Palisades Medical Center in North Bergen.
